' Application September 26, 1946, Serial No. 699,431

The present invention relates to new and useful improvements in loomsand more particularly to a warp tension attachment therefor.

An important object of the present invention is to provide a simple andpractical warp tensioning attachment for looms of small size whicheliminates the necessity of using a. warp beam thereby saving time inthe warp preparation and lowers the cost of the loom construction.

A further object of the invention is to provide an attachment of thischaracter of simple and practical construction, which is efflcient andreliable in operation, relatively inexpensive to manufacture andotherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had tothe accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure l is a fragmentary side elevational view of a loom showing thewarp tensioning attachment in position thereon.

Figure 2 is a front elevational view.

Figure 3 is a top plan view,,and Figure 4 is an enlarged fragmentarysectional view taken substantially on the line 44 of Figure 2.

Referring now to the drawings in'detail wherein for the purpose ofillustration 1 have disclosed a preferred embodiment of the inventionthe numeral 5 designates the rear vertical beam of the loom frame and 6and 'l the upper and lower longitudinal beams, the rear ends of thebeams 6 being connected by an upper transverse beam 8 while the rearends of the beams I are connected by a lower transverse beam 9.

A conventional form of comb I is secured in a horizontal position to thebeam through which the yarn l 1 passes in an upward direction forwardlyto the harnesses and other conventional parts of the loom designatedgenerally at I2.

The yarn ll passes over a transverse block l3 secured to thelongitudinal beams 6 adjacent the rear ends-thereof, the block having agroove M in its upper surface.

A tension roll is shown at 15 which is seated in the groove [4 with aslight clearance therefrom, the yarn passing under the roll.

A cord or other flexible member 18 extends over each end of the roll 15,one end of the cord being attached to the vertical beam 5 by means ofscrew eyes or the like II, the other end of the cords being attached tothe upper ends of 65 2,329,374

2 Claims. (Cl. 139-97) coil springs I8 which have their lower endssecured to the lower longitudinal beams I. The block l3 may be providedwith openings l9 through which the cords l6 freely pass.

In the "operation of the device the yarn ll passes upwardly through 'thecomb Ill which straightens and delivers the yarn evenly between thetension roll l5 and the grooved block l3, the springs l8 exerting adesired tension on the yarn.

In view ofthe foregoing description taken in conjunction with theaccompanying] drawings it is believed that a clear understanding of gthe construction, operation and advantages of the device will be quiteapparent to those skilled in this art. A more detailed description isaccordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by'the spirit of theinvention as herein described and the scope of the appended claims.

I claim:

1. A warp tensioning attachment for looms comprising a grooved blockover which strands Ofyarn are drawn, a roller seated on the block, aflexible member extended over the roller and slidably extended throughsaid block, and coil springs anchoring the flexible member to a part ofthe loom to yieldably urge the roller in the groove.

2. A warp tensioning attachment for looms comprising a grooved blockover which strands of yarns are drawn, a roller seated on the block, aflexible member extended over the roller and slidably extended throughsaid block toyieldably maintain the roller seated in the groove of theblock.
